UNITED STATES PATENT OFFICE.

HENRY ELING, OF NEW YORK, N. Y.

BASIN STOP-COCK.

Specification of Letters Patent No. 13,457, dated August 21, 1855.

To all whom t may concern Be it known that I, HENRY ELING, of the city,county, and State of New York, have invented a new and usefulImprovement in Basin Stop-Cocks; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming part of thisspecification, in which,-

Figure 1, is a vertical central section of a basin stop cock, with myimprovement applied to it. Fig. 2, is a horizontal section of the same,through the line ai, of Fig. 1.

Similar letters of reference in each of the two figures, indicatecorresponding parts.

Hy invention relates particularly to the basin cock, employing a risingand falling screw valve, and is designed to render it capable of havingits valve adjusted in case it should open too soon or not suticientlywide when the stem of the' cock is brought to a proper position over thebasin.

The nature of said invention consists in having the cap of the valvemade independent of the nut which confines it, and of such construction,that by simply loosening the nut, it may be turned to the right or leftand the valve adjusted so as to open and close at the proper time and tothe extent desirable.

To enable others skilled in the art to make and use my invention, I willproceed to de scribe its construction and operation.

A, represents the stationary part of the cock; B, the movable part; C,the cap made tapering upward and resting on a shoulder a., formed on theinterior of B; D, the nut for conning the cap; it is made tapering tocorrespond with the cap, and independent of the cap in order that thevalve may be adjusted; E, the stem of the cock, and F, the valve havinga female thread b, cut in it and resting on a seat c, formed on thestationary part, A, and screwing on the male screw (Z, formed on the capC. This valve is prevented from turning by two pins or stops d', oZ,cast on it which t and work in vertical slots, d, d, as shown in Figs. 1and 2.

G, is the barrel or clock spring arranged in the chamber of the movablepart B, below the valve seat, one end being attached to said movablepart and the other end to the stationary part as shown, and owing tobeing thus arranged serves for opening and closing the valve.

Owing to the screw c, being fast on the cap C, and the valve preventedfrom turning with it, by means of the pins d1, d1, and slots (Z2, d2, itmay be seen that by turning the stem F, a quarter of a revolution orfrom the position shown in black to the position shown in red in Fig. 2,the valve will be caused to rise and open as shown in red in Fig. l, thescrew d, taking into the thread ZJ, of the valve and causing it thus torise and open. The valve of course falls and closes as the stem E, againassumes or is caused to assume its position by the spring G.

The nut D, screws into a thread f, cut in the upper end of the movablepart of the cock and when screwed down as shown in Fig. l, serves forconfining the cap, securing it in its place and prevents it turningindependent of the part B. By loosening this nut, the cap can be turnedand if necessary the valve adjusted up or down the adjustment beingcaused by the screw c, taking into the thread a, of the valve andcausing the valve to rise or fall according as the cap is turned.

I do not claim closing a cock by means of a spring when said cock is notprovided with a screw valve, but

vWhat I do claim as my invention and desire to secure by Letters Patent,is-

Making the cap C, independent of the nut D, so that by simply looseningthe nut, the cap may be turned and the valve adjusted, substantially asdescribed.

HENRY BLING.
